Chrysanthemum plant named ‘Yovicki’

ABSTRACT

A distinct cultivar of Chrysanthemum plant named ‘Yovicki’, characterized by its uniformly mounded plant habit; freely branching growth habit; dark green foliage; uniform flowering; decorative-type inflorescences that are about  5.4  cm in diameter; attractive golden bronze ray florets that are dark bronze when opening giving a bi-colored appearance to the inflorescence; numerous inflorescences per plant; and excellent garden performance.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Dendranthema grandiflora and hereinafter referred to by the cultivar name Yovicki.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.

The new cultivar originated from a cross made by the Inventor in Salinas, Calif., in December, 1995, of the Dendranthema grandiflora cultivar Jean, disclosed in U.S. Plant Pat. No. 10,901, as the female, or seed, parent with an unidentified proprietary seedling selection as the male, or pollen, parent.

The cultivar Yovicki was discovered and selected by the Inventor as a flowering plant within the progency of the stated cross in a controlled environment in Alva, Fla. in November, 1996. The selection of this plant was based on its desirable inflorescence form, attractive ray floret color and excellent garden performance.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Alva, Fla. has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yovicki has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yovicki’. These characteristics in combination distinguish ‘Yovicki’ as a new and distinct cutivar:

1. Uniformly mounded plant habit.

2. Freely branching, dense, full plants.

3. Dark green foliage.

4. Uniform flowering.

5. Decorative-type inflorescences that are about 5.4 cm in diameter.

6. Attractive golden bronze ray florets that are dark bronze when opening giving a bi-colored appearance to the inflorescence.

7. Numerous inflorescences per plant.

8. Excellent garden performance with the blooms lasting at least three weeks.

Compared to plants of the parent cultivar, Jean, plants of the new Chrysanthemum are more uniformly mounded, flower about one week later under natural season conditions, and differ in ray floret color as plants of the cultivar Jean have light pink-colored ray florets.

Plants of the new Chrysanthemum are similar to the cultivar Viking, disclosed in U.S. Plant Pat No. 5,326. However in side-by-side comparisons under commercial practice, plants of the new Chrysanthemum are more uniformly mounded and flower more uniformly than plants of the cultivar Viking.

Plants of the new Chrysanthemum can also be compared to the cultivar Empire Harmony, disclosed in U.S. Plant Pat. No. 11,830. However in side-by-side comparisons under commercial practice, plants of the new Chrysanthemum differ from plants of the cultivar Empire Harmony in the following characteristics:

1. Plants of the new Chrysanthemum are slightly larger than plants of the cultivar Empire Harmony.

2. Plants of the new Chrysanthemum have larger and darker green leaves than plants of the cultivar Empire Harmony.

3. Plants of the new Chrysanthemum have larger inflorescences than plants of the cultivar Empire Harmony.

4. Ray floret color of plants of the new Chrysanthemum is richer bronze than ray floret color of the cultivar Empire Harmony.

5. Plants of the new Chrysanthemum flower about one week earlier than plants of the cultivar Empire Harmony under natural season photoperiodic conditions.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum. The photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Chrysanthemum. The photograph comprises a top perspective view of a typical flowering plant of ‘Yovicki’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Pendleton, S.C., under conditions which approximate those generally used in commercial garden Chrysanthemum production. One rooted cutting was planted in a 15-cm container on Jul. 26, 1999 and plants were grown under natural season conditions. Plants were not pinched, that is, the terminal apex was not removed to enhance branching. Measurements and numerical values represent averages for typical flowering plants.
